VEHICLE VENTILATING DEVICE Filed Dec. 11, 1950 INVENTOR. JOHN K. RE E D BYWW' ATTORNEY Patented Jan. 15, 1952 UNITED STATES PATENT OFFICE John Kenneth Reed, Charlevoix, Mich. Application December 11, 1950; Serial No. 200,241

This invention relates to automobile accessories and has particular reference to a device for stopping the whistle and noise of rushing air caused at high speed travel, when the ventilating wing or pivoted window panel of the automobile is a device which will control the outward flow of air from a vehicle body when a ventilator is open and a vehicle is traveling at a high rate of speed.

The foregoing and other objects and advantages of the invention will become more apparent as the description proceeds, reference being made from time to time to the accompanying drawings, forming part of the within disclosure, in which drawings:

Fig. 1 is a fragmentary perspective of the interior of an automobile from which the device embodying the invention is mounted.

Fig. 2 is a section taken on the line 22 of Fig. 1, with the sealing gaskets between the mullion and the ventilator and the mullion and the window panel removed.

Fig. 3 is an enlarged perspective view of the device embodying the invention.

Referring now more particularly to the drawings, it will be understood that in the embodiment herein disclosed, the reference character 1 generally indicates an automobile body having a door 8 and a conventional pivotable window panel or ventilator 9, which is shown in Fig. l as being in an open position. A division bar or mullion l separates the ventilator 9 from the principal pane of glass H of the door. The door glass H is shown in lowered position in Fig. 1, although it will be understood that the glass H will be in elevated position to effect the best results with the use of the device embodying the invention.

The parts just described are conventional parts of an automobile and form no part of the invention except as combined with the elements which I will now describe:

My improved ventilating accessory consists of a length of transparent plastic material l2, which is substantially of the same length as the mullion Ill, to which it is secured by means of a V-shaped spring clip l3, the latter being riveted, as at M, to the member I2. The spring clip I3 has bent and rebent terminal portions 15 and it which Claims. (Cl. 296-44) f .2 I I are adapted to clamp around the rolled edges I] and H] of the mullion Ill. The metal comprising the spring clip I3 is of such thickness as not to interfere with the raising and lowering of the window II, the leading edge of which travels in the channel IQ of the mullion.

The plastic member I2 is substantially flat throughout the greater part of its length and width, but has a slight radius formed adjacent its leading edge as shown in Figs. 2 and 3. The device may be used on either side of the vehicle by simply inverting it.

When the device is positioned on the left-hand door of the vehicle as shown in Figs. 1 and 2, the clip [3 engages the inside edges of the mullion l0, so that the member I2 is directed toward the interior of the automobile and along the radius 20 curves slightly toward the front of the vehicle as shown in Figs. 1 and 2. When so installed and the automobile is traveling at a high rate of speed with the ventilator 9 open as shown in Fig. 1, the air from the interior of the vehicle body will be drawn outwardly by reason of the vacuum created along the trailing edge of the ventilator 9 by the air outside of the vehicle being deflected outwardly by the ventilator 9. The air being drawn outwardly from the interior of the vehicle will assume a path substantially as shown by the directional arrows in Figs. 1 and 2 and will describe a comparatively wide are as it passes the leading edge 2| of the member l2. The stream of air which passes around the leading edge 2| of the member [2 is comparatively wide and its velocity is somewhat reduced because of the comparatively wide turn which it is forced to take by the member [2 as compared to the short turn it would normally take around the edge I! of the mullion II when the invention device is not employed.

I have discovered that it is the comparatively thin air stream being drawn outwardly at'high velocity and being bent sharply around the edge ll of the mullion In which causes the whistling and disturbing noises at the ventilator opening when the vehicle is traveling at high speed. These noises are reduced to a minimum or are entirely eliminated by the use of my device.

Having described my invention what I claim and desire to secure by Letters Patent is:

1. A device of the character described for use with a vehicle body having a ventilator Window pivoted on a vertical axis and a mullion in back thereof, comprising a sheet of transparent material of substantially the same length as said mullion, said sheet of material being substantially 3 flat throughout its length and width except for a slight radius formed adjacent the leading edge thereof, said sheet being directed toward the front of the vehicle and means for attaching said sheet of plastic material to said mullion.

2. The structure defined in claim 1, in which said last named means consists of a V-shaped spring clip having inturned terminal portions adapted. to-fin ag e.opposite edges ofssaidmullion.

3. Adevicefofithe character described for use on the mullion of an automobile at the rear of a ventilator window which is pivoted on a vertical axis, comprising a sheet of plastic material of substantially the same length as said mullion, said sheet of material being directed toward the interior of said automobile and having a portion thereof curved toward the .front 'of'said automobile, there being means on said sheet of material for attaching the same tosaid mullion.

, 4. The structure defined in claim 8, in which said' last named'means comprises a substantially SKA device of the character described for use in back of a vehicle ventilator window, which is pivoted ona-vertical axis in combination, a sub- ,sheethaving .the radius :being directed toward the-frontof the-vehicle.
